4. Start Eclipse and open “LLRP Client” perspective

5. First time start-up
When Eclipse loads the LLRP Client for the first time, the Health Check function is triggered to validate whether the environment is ready for use. If any significant error is detected (for example, if the folders are corrupted or the database table doesn’t exist), this dialog will popup at startup.
You can fix the reported problems by just pressing the “Fix It!” button.

9. Project Navigator
The LLRP client needs a Eclipse project to store editable messages. You can either define a specific project in the Preference Page, or use the default “LLRP_CLIENT” project folder.
The LLRP client automatically generates two folders for the project folder:
Draft: to hold the pre-built sample LLRP message files;
Temporary: to hold the incoming message files when users load them from the repository.
When you modify the files in the “Temporary” folder, the changes will not be written to the Repository. In addition, if you purge the JavaDB, the files under “Temporary” folder will not be removed.
Every time Eclipse starts up, the “Health Check” can detects whether the project exists or the folder structure is corrupted. If yes, you can easily recover it by the “Auto Fix” function.
